I've made some progress on suspend with FreeBSD on my Thinkpad T14 gen2i

Turns out there's a simple BIOS setting to enable S3 suspend—now it works!
Sort of, that is:

- I'm getting tons of errors from the intel wifi driver on resume, and have to do `service netif restart` to get it working again
- The screen isn't locked on suspend; guess I have to add an rc.d script for that
- For some reason, the shutdown button in Xfce doesn't shutdown anymore after I've resumed from suspend, but only logs me out

But I'm getting closer, and learning a lot in the progress. More debugging tomorrow!

@kedara iwlwifi?
@grahamperrin yes, sorry, had to specify that.
@grahamperrin so if I understand correctly, there is a call for testing on 16 before 15.1 is released? I'm new to FreeBSD as you can tell, how would I test this while keeping my laptop @ the 15 release version? Can I install to a separate ZFS dataset? The intel card is an AX210 btw, if relevant.
